355nm pulsed ultraviolet laser source Marking: Eliminate the food “date game”

Food safety has been a hot topic in recent years. Nowadays, people no longer focus on the packaging, taste, price, but pay more attention to food safety. People believe that the shelf life of can be faked by removing the old warranty date and printing a new warranty date.

Bei Verwendung einer Lasermarkierung können das Produktionsdatum und andere auf der Verpackung markierte oder eingravierte Informationen nicht verändert oder verändert werden. Die Lasermarkierung ist ein dauerhafter Druck auf dem Objekt.

Dies ist einer der Artikel über die Anwendung von Lasermarkierungen in der Industrie für Laser-Datumscodierungsanwendungen. Es beschreibt die Vorteile und den Nutzen der Laser-Datumskennzeichnung, da es sich um eine dauerhafte Codierung auf dem Verpackungsgegenstand handelt, egal ob es sich um Kunststoff, Glaspapier oder Holz handelt.
